TrueRC X-Air 5.8 Crosshair Antenna MK II (Factory 45° SMA) - LHCP

Gain a competitive edge in crowded RF environments with the TrueRC X-Air 5.8 Crosshair Antenna MK II (LHCP). This model is built with Left Hand Circular Polarization and a factory-integrated 45-degree SMA connector, making it the ultimate solution for analog pilots looking to escape the noise of standard RHCP signals or digital users requiring SMA connectivity.

The X-Air MK II redefines what is possible in antenna miniaturization. Using advanced aerospace-grade PCB technology, TrueRC has packed the performance of a large phased-array antenna into a sleek 32mm profile. It delivers a commanding 9.5-10.5 dBic gain and a wide 120-degree beamwidth, providing excellent penetration through trees, buildings, and other obstacles. This allows you to fly with the confidence of a directional antenna without the hassle of keeping your head perfectly still.

The integrated 45-degree SMA Male connector is a game-changer for durability and convenience. By building the angle directly into the antenna's feed, TrueRC has eliminated the need for heavy, signal-degrading adapters. The result is a direct, secure fit for FatShark, Skyzone, and Orqa goggles equipped with SMA-based receiver modules like the ImmersionRC RapidFire or TBS Fusion.

Whether you are a drone racer seeking cleaner video on the LHCP bands, a university research team conducting swarm testing, or a government sUAS operator requiring reliable redundant links, this antenna delivers professional-grade performance. Its massive bandwidth (5.1GHz to 6.7GHz) ensures compatibility with every available FPV channel.

Key Features:

• LHCP Polarization: Ideal for racing events to avoid RHCP interference or for separating video feeds in multi-pilot operations.

• Integrated 45° SMA Mount: Directly mounts to goggles at the optimal reception angle; no adapters required.

• High-Gain Performance: Delivers ~10dBic gain for extended range and deep signal penetration.

• Rugged & Compact: Low-profile design reduces leverage on goggle connectors and withstands the rigors of field use.
